Anyone who reads Liberty Blitzkrieg consistently will be aware of my disdain for the company Facebook. There are many reasons for my negative sentiments, but at its core is the company’s complete disrespect toward its own users.

Many of the social network’s users were annoyed — if not outraged — to learn that the free app was “mandatory” if they wanted to continue using Facebook on the go.

Some refused to download the app, claiming that the situation had prompted them to quit Facebook altogether.

Some of those who downloaded the app may be thinking twice this week about keeping the app around, however, in light of one iOS forensics and security researcher’s recent assertions that Messenger is tracking more data than most people realize.

In an email to VICE’s Motherboard, Zdziarksi told reporter Matthew Bragathat Facebook logs “practically everything a user might do within the app.”

“[Facebook is] using some private APIs I didn’t even know were available inside the sandbox to be able to pull out your WiFi SSID (which could be used to snoop on which WiFi networks you’re connected to) and are even tapping the process list for various information on the device,” he wrote.
